Abstract (en)
[origin: EP1727230A1] Four SP4T switches (3 1 - 3 4 ) are grouped in twos to form two switch pairs. First conductive lines (4 11 - 4 14 , 4 21 - 4 24 ) are arranged in fours between the SP4T switches (3 1 , 3 4 ; 3 2 , 3 3 ) constituting the switch pairs. Each of four second conductive lines (5 1 - 5 4 ) connects to a corresponding one of different conductive lines of the first conductive lines which connect to the respective switch pairs. The first and second conductive lines are arranged on a dielectric layer having a lower surface on which a ground conductor (6) is formed. The dielectric layer has a two-layer structure. The first conductive lines are arranged on the first dielectric layer as a lower layer. The second conductive lines are arranged on the second dielectric layer as an upper layer. This arrangement makes it possible to attain a reduction in the size of a matrix switch and a reduction in loss and allow broadband operation.
